During Sunday night's Little League Classic between the New York Mets and Seattle Mariners, Major League Baseball commissioner Rob Manfred talked about the possibility of not just expansion, but also a total overhaul of the leagues as we know them.

When MLB expansion comes up, which cities will get new teams is always the first topic. But there's another factor that will impact the entire sport: How will MLB realign its divisions -- and structure its playoffs -- to accommodate those new franchises.
